Fuse Block: Description and Operation
Description
DESCRIPTION
An electrical Junction Block (JB) (1) is concealed behind the left outboard end of the instrument panel cover. The JB combines the functions previously
provided by a separate fuseblock module and relay center, serves to simplify and centralize numerous electrical components, and to distribute electrical
current to many of the accessory systems in the vehicle. It also eliminates the need for numerous splice connections and serves in place of a bulkhead
connector between many of the engine compartment, instrument panel, and body wire harnesses.
The molded plastic JB housing has integral mounting brackets that are secured with two screws to the left instrument panel end bracket. The left end of
the instrument panel cover has a snap-fit fuse access panel that can be removed for service of the JB. A fuse puller and spare fuse holders are located on
the back of the fuse access cover, as well as a fuse layout to help ensure proper fuse identification.
The JB unit cannot be repaired and is only serviced as an assembly. If any internal circuit or the JB housing is faulty or damaged, the entire JB unit must
be replaced.
